Redis Error

Michael Pfaff

I've gotten this error a couple times in the past couple days:

MISCONF Redis is configured to save RDB snapshots, but is currently not able to persist on disk. Commands that may modify the data set are disabled. Please check Redis logs for details about the error.

When I check my Redis log, I see this:

1318:M 11 Jun 07:03:29.017 # Can't save in background: fork: Cannot allocate memory
1318:M 11 Jun 07:03:35.038 * 10 changes in 300 seconds. Saving...

A whole bunch.

I'm currently on a 1GB / 30GB droplet with DigitalOcean. I don't get a crazy amount of traffic on our site.

Any ideas what's up?

It also appears I don't have virtual memory enabled. Could this solve the issue?

              total        used        free      shared  buff/cache   available

@Michael-Pfaff yes it might help to add some swap

Yeah, it was a RAM issue. Upgraded the server and all is well now.
